About

The purpose of this research study is investigate a new and validated urine test which predicts the likelihood of high grade prostate cancer on an initial prostate biopsy The current protocol has two objectives; one is to further assess and evaluate the performance of the urine test in men already scheduled for initial prostate needle biopsy (cohort (group) 1) and two, to evaluate how the results of the urine test influences the decision process for determining whether to perform a prostate biopsy (cohort (group) 2).

Full description

Primary Objective(s)

• Confirm performance of the ExoDx Prostate (IntelliScore) (EPI) utilizing a designated collection vessel for men presenting for their initial prostate biopsy with an elevated Prostate-specific antigen (2-10 ng/mL).
• Evaluate impact of the confirmed ExoDx Prostate (IntelliScore) on the decision to perform an initial prostate biopsy for men presenting with an elevated Prostate-specific antigen (2-10 ng/mL).

Secondary and Exploratory Objectives

• Assess physician satisfaction with the ExoIntelliScore Prostate report including test result presentation, graphics and interpretation.
• Assess patient satisfaction for ease of understanding test results and role on decision process to have a biopsy.
• Determine the medical economic impact of the ExoIntelliScore Prostate in the prostate biopsy decision process.
• Correlation of the ExoIntelliScore Prostate score with the actual biopsy result.

Enrollment: 532 patients

Sex: Male

Ages: 50+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• 50 years of age
• Clinical suspicion for prostate cancer
• Elevated Prostate-specific antigen between: 2.0 - 10 ng/ mL
• No clinical history of a prior negative biopsy

Exclusion criteria

• History of prior prostate biopsy.
• Use of medications or hormones that are known to affect serum Prostate-specific antigen levels within 3-6 months of study enrollment.
• Clinical symptoms of urinary tract infection (including prostatitis) at the time of enrollment.
• History of prostate cancer.

• No known hepatitis (all types) and/or HIV documented in patient's medical record.
• Patients with history of concurrent renal/bladder tumors.

Trial design

532 participants in 2 patient groups

Cohort 1

Description:

Enroll up to 500 patients to confirm performance of ExoDx Prostate IntelliScore (EPI) for men scheduled for initial biopsy. The treating physician will collect a urine sample from from a consented subject to test before their scheduled prostate biopsy (during your established clinic visit).

Cohort 2

Description:

Enroll up to 500 patients to evaluate how the results of the urine test influences the decision process for determining whether to perform a prostate biopsy. The treating physician will collect a urine sample for testing and 2 weeks later discuss whether to perform a prostate biopsy with the subject knowing the results of the urine test and comparing them to the overall consensus report from Cohort 1 as well as other clinical factors the treating physician would otherwise use to determine whether they should have a prostate biopsy.

Treatment:

Diagnostic Test: ExoDx Prostate Intelliscore
